Abstract
【Objective】 The aim of this study was to investigate the growth rate and composition of seed under temperature changes during early seed-filling (10 DAF and 32 DAF) in planta and in vitro and to determine the effects of temperature changes onfurther seed development and seed composition during early seed-filling stage. 【Method】 Three genotypes (Evans, low protein line; Proto, high protein line; and PI132.217, stable protein line) were grown in three growth chambers with the same optimum conditions of 27/20℃ until 10 DAF, then for 10 days the temperature in each growth chamber was adjusted to one of three day/night temperature regimes: 35/27℃ (Ho); 27/20℃ (Mo), or 20/12℃ ( Lo). At 20 DAF, seeds collected from each genetic line in each growth chamber were cultured in vitro for 12 days with three day/night temperature regimes: 35/27℃ (H); 27/20℃ (M), or 20/12℃ (L) with 75 mmol·L-1 glutamine and 142 mmol·L-1 sucrose. 【Result】 Cultured in planta, from 10 DAF to 20 DAF, the FW and DW of seeds were not marked different by different temperature treatments, but greater seed protein concentration was obtained when seed grew in Mo; the greatest seed oil accumulation was in Ho, with 75% of the final oil concentration, about two-fold of Lo, which had a final concentration of oil at 35%. In vitro, from 20 DAF to 32 DAF, the seeds collected from planta with Ho cultured at different temperatures gave higher FW and DW than those from Mo and Lo, suggesting that the temperature of the early stage before 20 DAF has a highly potential impact on later seed development. Cotyledon of growth rate (CGR) increased when temperatures were increased, but CGR was twice as high in MoH than in LoM. CGR was two-fold less in HoL when temperatures was decreased by 16oC than in HoM by 8oC, indicating that a high temperature would increase the CGR, but a sharp drop in temperature would be disastrous to further seed development. However, a net increase of protein concentration of cotyledon during 12 days was much higher when the temperature was increased by 8℃ in LoM and MoH and decreased by 8℃ in HoM and MoL. 【Conclusion】 The temperature in early stage impacted on seed growth which will influence on further seed development and composition. Higher temperature in early seed fill stimulated the oil accumulation and restricted protein accumulation. Genetic differences in response of CGR and seed composition to temperature changes at early seed-filling stage were found that PI132.217 is a no-sensitive line. These results have provided an evidence that the selection of a proper planting day and breeding a new cultivar of soybean with no-sensitive to temperature are very critical to increase seed yields with higher oil and protein concentration in face of more frequently temperature change in the future.
